Abstract:

Three new oxalato organotin IV adducts and complex have been synthesized, their infrared and Mössbauer studies carried out. In the three compounds the coordination number of tin IV is 6, the SnMe2 residue being linear, the oxalate anion behaving as a bichelating or a monocoordinating ligand. The structures, suggested from spectroscopic data, are all discrete. The key role of the non symmetrical cation Cy2NH2+ involved in NH----O and NH----Cl hydrogen bonds is noteworthy.

Keywords:

tin IV, adducts, complex, trans octahedrally coordinated SnMe2 residue, hydrogen bonds.
